AIR-PISTOL.

To all wlwm it may concern:

VBe it known that we, CHARLES W. MA'LZ and CLYDE II. HALE, bothvcitizens of the United States, and residents of Evanston, in the.county of Cook and State of Illinois, have invented a new and ImprovedAir- Pistol, of which the following iswa full, clear, and exactdescription.

Our invention has for its object to provide an air pistol cheap inconstruction, and which has a cylinder with a chamber,

Yat one end of which there is a diaphragm movable outwardly when the airpressure in the chamber reaches a .predetermined point, the diaphragmbeing connected with a valve `commanding .communication between thechamber and the pistol barrel so that when the pressure in the chamberis increased, as stated, the valve will belopera'ted to permit theescape of the air under pressure in the pistol barrel.

Additional .objects of the invention will appear in the followingspecification in which the preferred form of vtheinvention is discloseIn the drawings similar reference characters denote similar parts in allthe views, in which- Figure 1 is a side elevation of the pistol, partsbeing broken away to illustrate the construction; and

Fig. 2 is a plan view of the cylinder and the operating bulb, the top ofthe cylinder being broken away to illustrate the construction ofthevalve.

By referring to the drawings it will be seen that the pistol isconstructed with a cylinder 5 having a diaphragm 6 at its rear end, thisdiaphragm'6 being preferably constructed of metal and being normallydisposed inwardly, as illustrated in Fig. 1 of the drawings. At the topof the front 7 of the cylinder there is an opening 8 through which abarrel 9 is disposed, the rear end 10 of this barrel 9 within thecylinder chamber 11 forming a valve seat at 12, against which isnormally disposed a valve 13. This valve 13 is secured to a valvespindle 14., the forward end of which is disposed in a guideway 15 in adepending member 16. To the rear of the valve spindle 14C there issecured a stop 17, a spring 18 being mounted on the valve spindle 14:between the stop 17 and the valve 13.

Disposed in the chamber 11 and secured to the cylinder 5, there is abracket 19 to Specification of Letters Patent. Patllted July 17, 191W.

. Application mea september 29, 191e. serial No. 122,844.. y'

which is fulcrumed at 20 aylever 21, this ,l

vlever 2l being disposed between the spring- 1.8 and the stop 17, andhaving an orifice 22 through which the valve spindle 14: is disposed.The diaphragm 6 is connected with the lever 21 by means of a link 23. i

Depending from the bottom of the cylinder there is a'neck 24, a bulb 25being mounted on this neck.

In the barrel 9 there is preferably a stop 26 to limit the rearwardmovement `of a bean 27 which may be fired with the pistol.

'IVhen a bean 27 is disposed in the pistol barrel 9 adjacent the-stop26, and the bulb is quickly compressed, the increase in air pressure inthe chamber 11 will move the diaphragm 6 rearwardly, which, by means ofthe link 23, will move the lever 21 rearwardly, the lever 21 when itengages the stop 17, serving to move the valve 13, thereby permittingthe air under pressure in the chamber to force the bean 27 forwardly andout of the barrel 9. The spring 18 makes it possible for the valve 13'to? remainu'nseated suiiiciently long to permit air to enter the chamber11 and the bulb 25, so that the pistol may be fired a second time.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. In an air pistol, a cylinder with a chamber having an outlet, a valvefor commanding the outlet, a diaphragm having a surface exposed in thechamber, means by which the valve is adapted to be operated by thediaphragm, and means to increase the air pressure in the chamber.

2. In an air pistol, a cylinder' with a chamber having an outlet, adiaphragm having a surface exposed in the chamber, a valve commanding'the outlet and provided with a valve spindle, a stop on the valvespindle, a spring on the valve spindle between the valve and the stop,means operable by the diaphragm and engaging the valve spindle betweenthe spring and the stopfor operating the valve, and means for increasingthe air pressure in the chamber.y

l3. In an air pistol, a cylinder with a chamber having` an outlet, adiaphragm having a surface exposed in thechamber, a valve commanding theoutlet and provided with a valve spindle extending in the direction ofthe diaphragm` a stop on the valve spindle, a spring on the valvespindle between tbe valve andthe step, means eperable by the diaphragmand engaging the valve spindle between the spring and the stop foroperating the valve, and means for increasing the air pressure in thechamber.

4. In an air pistol, a cylinder with a chamber having an outlet, adiaphragm having a surface exposed in the chamber, a valve commandingthe outlet and provided with a valve spindle, a stop on the valvespindle, a spring on the valve spindle between the stop and the valve, alever engaging the valve spindle between the spring 'and the stop, alink connecting the dia- -phragm with the lever, and means forincreasing the air pressure in the chamber.

5.7In an air pistol, a cylinder with a chamber having an outlet, a valvecommanding the outlet, a diaphragm having a surface exposed in thechamber, a leve'r, means by which the lever is adapted to operate thevalve, a link connecting the diaphragm with the lever, and means toincrease the air pressure inthe chamber.

6. In an air pistol, a cylinder with a chamber having an outlet, adiaphragm having a surface exposed in the chamber, a valve commandingthe outlet and having a valve spindle extending in the direction of thediaphragm, a stop on the valve spindle, a spring on the valve spindlebetween the stop and the valve, a lever ulcrumed at I Copies of thispatent may be obtained for one end and engaging the valve spindle at itsother end between the spring and the stop, a link connecting thediaphragm with the lever, and means for increasing air pressure in thechamber.

7. In an air pistol, a cylinder having a chamber, a diaphragm at therear of the chamber, a barrel extending from a point adjacent the top ofthe front `or" the cylinder, means at the bottom of the cylinder forincreasing air pressure in the chamber, valve means commandingcommunication between the chamber and the barrel, and means by which thediaphragm is adapted to operate f the valve means.

8. In an air pistol, a cylinder having a chamber, a diaphragm at therear of the chamber, a barrel extending from a point adjacent the top ofthe cylinder, means at the bottom of the cylinder for increasing the airpressure in the chamber, a valve commandingcommunication between thechamber and the barrel and provided with a valve spindle, a, stop on thevalve spindle, a spring disposed on the valve spindle between the valveand the stop, a lever having its upper end engaging the valve spindlebetween the spindle and the stop, and a link connecting the diaphragmwith the lever.
